Abstract
Abstract Stable, aqueous, colloidal synthetic resin compositions comprising: (1) from about 0.1% by weight to about 60% by weight of a colloidal synthetic resin; and (2) from about 0.01% by weight to about 2% by weight based on the dry solids weight of the colloidal synthetic resin, of an aluminum hydroxy salt of a high molecular weight, water-soluble, polymeric, polycarboxycontaining thickening resin; and methods of applying the synthetic resin compositions to porous, absorbent materials and controlling the migration or spreading thereon or penetration thereinto by applying the synthetic resin compositions to the porous, absorbent materials and substantially immediately diluting the synthetic resin composition to substantially immediately coagulate and precipitate the synthetic resin composition.
